    Plane wilt (canker stain disease) Pest Alert

    Lead Author: Forestry Commission
    Plane wilt, also known as canker stain disease, is a serious disorder of plane trees, which are important amenity trees in the parks and avenues of many European cities. The disease is caused by the fungus Ceratocystis platani, which is present in the USA and Europe, but considered to be indigenous only to North America. […]

    Xylella fastidiosa – Pest Alert

    Lead Author: Forestry Commission
    Xylella fastidiosa is a disease-causing bacterium that affects a wide range of important woody plants and broadleaved trees. It invades the xylem vessels that transport water throughout plants, and causes symptoms ranging from leaf scorch to tree dieback and death. In the natural environment it is transmitted by xylem-fluid feeding insects such as leafhoppers. Until recently […]

    Future Proofing Plant Health

    The Future Proofing Plant Health project aims to provide evidence for the implementation of the GB Plant Biosecurity Strategy. It will focus on strategic areas related to new and emerging pests and diseases (prevention, detection, control, resilience), as well as identifying priority pests, diseases and pathways.

    In planta detection used to define the distribution of the European lineages of Phytophthora ramorum on larch (Larix) in the UK

    Lead Author: K. M. King
    UK distribution of Phytophthora ramorum evolutionary types provided by new testing method. By developing a new molecular-based testing method based on PCR techniques, Forest Research scientists have been able to examine the distribution of the two main lineages of Phytophthora ramorum responsible for the major epidemic on larch (Larix spp.) in the UK. In a paper […]

    Oriental Chestnut Gall Wasp

    Lead Author: Simon Morath
    News of a recent unwelcome discovery and how ‘citizen science’ can play an important role in surveying and identification. An overview of the 2015 discoveries of Dryocosmus kuriphilus (Oriental chestnut gall wasp; OCGW) in European sweet chestnut (Castanea sativa) trees in Farningham Woods, Kent and St Albans, Hertfordshire, was published in Quarterly Journal of Forestry. It […]

    Hot-water treatment as a possible method for eradicating Chalara fraxinea (Hymenoscyphus pseudoalbidus ) infection from ash fruits (Fraxinus excelsior L )

    Lead Author: Shelagh McCartan
    Treating ash seeds with hot water may kill Chalara infection Immersing ash seeds in 44°C water for 5 hours may eradicate Chalara infection in ash seeds without significantly reducing the viability of the seeds. Forest Research scientists have published the results of this trial in Quarterly Journal of Forestry. Batches of ash fruits were subjected to […]

    Pine-tree lappet moth

    This project is exploring the threat to UK forestry posed by the Pine-tree lappet moth (Dendrolimus pini) and whether it is an introduced pest species or a previously undiscovered resident.

    Green spruce aphid (Elatobium abietinum) research

    The project is analysing data on spruce aphid populations from forests managed using different silvicultural systems, to determine whether increasing the structural diversity of forest stands leads to a lower incidence of the pest and a reduction in damage.
